A Network Management system is developed for managing, controlling and optimizing a business network. It comprises of both software and hardware. However, often it is developed as a software to manage a network.
Network management solution offers a range of services. These include
Network monitoring - NMS oversees the network hardware to check if all the devices are functioning properly. Network administrators are notified if a problem is identified.
Device detection - when any new device attempts to establish a connection to the network, NMS identifies it so that it can be configured and added to the business network. This process is called device provisioning.
Performance analysis - An NMS can measure the past and current performance of a network. It also checks on the overall performance of a network or the performance of each devices and individual connections. For instance, the NMS may identify the activities of network where the amount of data passed in is almost the same as maximum bandwidth available.
Device management - An NMS manages a variety of devices from a central and single platform. It is deployed to modify settings or assists in device configuration after analyzing the performance.
Fault management - NMS instantly redirects the traffic in case if there is a failure of a section or a device - hence limits downtime. This is attained by a set of pre-configured policies. The network admins are notified if there occurs a flaw or fault in the network.
Network Management System is not required for a home network. Nevertheless, it is critical, to manage large business network with complex enterprise configurations. NMS is vital to maintain and monitor data centers, corporate networks and those that have multiple folds of connected devices. NMS is efficient to identify, repair, and update network equipment when required.
NMS software are deployed on a dedicated server or on premises, or controlled on site, or can be implemented as a service where the vendor provides the tools and software required for the enterprise to implement and monitor the network. NMS software helps to manage a huge variety of components associated with the network that were created by multiple vendors..
Deploying an on-premise NMS gives better control of the software and can be customized as per the required demands. An IT staff and required resources are required to take control of the software internally and also update it as and when required. Vendor-based NMS entitles for an instant return on investment, however, there is a higher probability for the network to get compromised if the vendor doesn't abide by the security compliance.
